backup is always available. Mirroring is typically used in mission-critical systems,
such as payroll, accounting, and ERP databases.
JBOD
Just a Bunch of Disks (JBOD) refers to a group of hard drives. In JBOD, the number
of logical drives is equal to the number of physical drives. This mode allows the
RAID System to operate as a multi-disk storage enclosure but provides no data
redundancy.
